Things worth knowing about "Ovarian Reserve"

Ovarian reserve refers to the number and quality of remaining eggs in a woman´s ovaries and is a key indicator of female fertility and reproductive potential.

What Is Ovarian Reserve?

The term ovarian reserve refers to the quantity and quality of a woman´s remaining eggs (oocytes) stored within the ovaries. It is a central measure of reproductive capacity, indicating how many eggs are still available for potential fertilization and pregnancy. As a woman ages, her ovarian reserve naturally declines -- both in the number of eggs and in their quality.

Causes of Diminished Ovarian Reserve

A reduced ovarian reserve can result from various factors:

Natural aging: Egg count declines more rapidly after age 35.
Genetic factors: Family history of early menopause or chromosomal conditions such as Fragile X syndrome.
Ovarian surgery: Previous procedures on the ovaries, for example to treat endometriosis or ovarian cysts, may damage ovarian tissue.
Chemotherapy and radiation therapy: Cancer treatments can permanently impair ovarian function.
Autoimmune conditions: Certain autoimmune processes may target ovarian tissue.
Primary ovarian insufficiency (POI): Premature decline of ovarian function before the age of 40.
Smoking: Nicotine accelerates the depletion of the follicular pool.

Symptoms and Signs

Diminished ovarian reserve often causes no obvious symptoms. Possible indicators may include:

Difficulty conceiving despite regular unprotected intercourse
Shortened or irregular menstrual cycles
Absent or infrequent periods
Hot flushes or other menopausal symptoms in younger women, which may suggest premature ovarian insufficiency

Diagnosis

Ovarian reserve is assessed using several diagnostic tools:

AMH (Anti-Mullerian Hormone)

Anti-Mullerian hormone (AMH) is produced by follicles in the ovaries and is considered the most reliable single marker of ovarian reserve. A low AMH level indicates a reduced egg count. This blood test can be performed on any day of the menstrual cycle.

AFC (Antral Follicle Count)

The antral follicle count (AFC) uses transvaginal ultrasound to count the small, resting follicles in both ovaries. A low AFC (fewer than 5 to 7 follicles per ovary) is considered a sign of reduced ovarian reserve.

FSH and Estradiol Levels

Follicle-stimulating hormone (FSH) is measured on day 2 or 3 of the menstrual cycle. An elevated FSH level may indicate diminished ovarian reserve. Estradiol is measured at the same time, as an elevated estradiol level can artificially suppress FSH values, masking a true increase.

Treatment and Options

Management depends on the degree of impairment and the patient´s individual fertility goals:

Assisted Reproductive Technologies

Ovarian stimulation: As part of in vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI), the ovaries are stimulated with hormones to retrieve available eggs.
Egg freezing (oocyte cryopreservation): Elective freezing of a woman own eggs, ideally before the age of 35.
Egg donation: When the ovarian reserve is severely depleted or exhausted, using donor eggs may be an option.

Lifestyle Modifications

Quitting smoking
Weight optimization
Stress reduction
A balanced diet rich in micronutrients such as folic acid, vitamin D, and coenzyme Q10

Hormonal Support

In cases of diagnosed primary ovarian insufficiency, hormone replacement therapy (HRT) may be prescribed to relieve symptoms of estrogen deficiency and protect bone health.

Relevance in Reproductive Medicine

Ovarian reserve is a critical parameter in fertility counseling and treatment planning. It influences the choice of treatment strategy, the expected response to ovarian stimulation, and the overall prognosis for assisted reproduction. Women who are trying to conceive should consider a fertility evaluation after 6 to 12 months of unsuccessful attempts -- or sooner if known risk factors are present.
